Is there possibly a Myotonia acquisita?

  • E. Thomasen


The symptom myotonia is according to Buchthal and Rosenfalck (1963) characterized by specific electromyographic features. They are: 1. Afteractivity following voluntary effort becoming less pronounced with repetition, 2. mechanical myotonia with sustained discharge with bursts of increasing and decreasing frequency, 3. spontaneous bursts of the same type, and 4. spontaneous action potentials of short duration.
